CHARACTERISTICS OF ELECTROCHEMICALLY PREPARED POLY-(1,4-DIMETHOXYBENZENE) ELECTRODE

Anodic oxidation 1,4-dimethoxybenzene (PDMB) leads to formation of a c onductive film deposited on platinum electrode if strict control of hu midity is maintained. A modified electrode was tested in several elect rolytic media for oxygen and hydrogen evolution reactions, offering a wider potential window for oxidation than for reduction. It is apparen t that oxidation of Fe(II) to Fe(III) is minimized in presence of poly -PDMB. Morphology of the deposit depends on deposition time. Conductiv ity of poly-PDMB, tested in solution, was found to be higher when morp hology of the deposit consisted in dimples arrangement. Silver deposit ion on the polymer surface was performed as qualitative proof of its c onductivity and to demonstrate that reactions are taking place on the polymeric matrix rather than on the platinum surface.
